Defrosting
Bleeding part of the moisture of cooling chambers in
form of frost and ice goes with the operation of the appli-
ance.
Thick frost and ice has an insulating effect, so it reduces
cooling efficiency as the temperature increases in the
cooling chambers, they need more energy.
At this type of appliance defrosting the cooling surface of
the refrigerator is automatic without any external interven-
tion.The thermostatic control interrupts the operation of
compressor at regular intervals for more or less time -
during this cooling is interrupted - the temperature of the
cooling surface goes above 0 °C due to interior heating
load of the compartment, so defrosting occurs. When the
surface temperature of the cooling surface has reached
+3 - +4 °C the thermostatic control restarts operation of
the system.
Melting water flows through defrost water outlet leaded
through the back into the evaporator tray maintained on
the top of compressor and evaporates due to its warmth.
Check and clean the outlet of melting water
coming during defrosting regularly - a label
inside the appliance warns you for this. If it is
clogged the melting water gathered can cause earli-
er failure as it can go to the insulating of the appli-
ance.
Clean the melting water outlet with the supplied pipe
scraper that can be seen in the figure. The pipe scraper
has to be stored in the outlet.
The most typical case of clogging up in the melting water
outlet when you put food wrapped in some paper into the
appliance and this paper contacts back plate of the
refrigerator and freezes to it. If you remove the food right
at this moment the paper will tear and it can cause clog-
ging up in the outlet by getting into it. So you are asked
to be careful - because of the above - when placing foods
wrapped in paper into the appliance.
In case of increased demand e.g. during heat-
waves, the refrigerator temporarily happens to
operate constantly - during this the automatic defrosting
does not work.
Remaining small ice and frost stains on back plate of the
refrigerator after defrosting period is not abnormal.
The freezer can not be equipped with automatic defrost-
ing set since the deep-frozen and frozen foods do not
endure melting temperature.
When small frost and ice occurs scrape off and remove
frost and ice coating with the supplied plastic scraper.
When ice coating is so thick that it cannot be removed
with the plastic scraper, the cooling gill have to be defrost-
ed. Frequency of defrosting depends on usage (generally
2-3 times a year).
Take the frozen foods out of the appliance, and put them
into a basket lined with paper or cloth. Store them in a
possibly cool place or replace them into another refriger-
ator.
Pull out the mains plug from the mains socket, so both
parts of the appliance are out of operation.
Open the doors of both parts of the appliance and clean
the refrigerator according to 'Regular cleaning'. Maintain
and clean the freezer as following:
Sweep off the melting water with a cloth or sponge in
direction of sides of the cooling plates. The melting water
swept down gathers in the outlet channel practically
formed in the bottom of the appliance and can be
removed according to figure.
Put an adequately high bowl or dish under the outlet.
The bowl in figure is not a piece of accessories to the
appliance!
Wipe the surfaces after defrosting and leading the water
out.
Put the mains plug into the mains socket and put foods
taken out back to their places.
It is recommended to operate the appliance at the highest
position of the thermostatic control for some hours so that
it can reach the sufficient storing temperature as soon as
possible.
